Abstract

In a series of articles (Pagin, 2004, 2009), Peter Pagin has argued that assertion is not a social speech act, introducing a method (which we baptize ‘the P-test’) designed to refute any account that defines assertion in terms of its social effects. This paper contends that Pagin's method fails to rebut the thesis that assertion is social. We show that the P-test is both unreliable (because it overgenerates counterexamples) and counterproductive (because it ultimately provides evidence in favor of some social accounts). Nonetheless, we contend that assertion is not fully social. We defend an intermediate view according to which assertion is only a partly social speech act: assertions both commit the speaker to a proposition (a social component) and present their propositional content as true (a non-social component). The upshot is that assertion is in some important respect social, although it cannot be defined solely in terms of its social effects.
